Abstract

The invention relates to the technical field of electrical materials, in particular to a graphene copper-based composite material and a preparation method and application thereof. The preparation method of the graphene copper-based composite material comprises the following steps: sequentially stacking a graphene layer and a second copper plate on a first copper plate to obtain a graphene interlayer blank sample; rolling the interlayer blank sample by adopting an accumulative roll-bonding welding method to obtain a rough blank; and enabling the rough blank is subjected to annealing treatment and cooling, thereby obtaining the graphene copper-based composite material. According to the preparation method of the graphene copper-based composite material, the high conductivity of graphene and the composite effect and the synergistic effect of a graphene copper composite system are utilized, a complete graphene diversion channel is formed in the material, and a high-conductivity cable material is obtained, has better conductivity and mechanical performance, and is widely used in the field of electricians.

Description

technical field [0001] The invention relates to the technical field of electrical materials, in particular to a graphene copper-based composite material and a preparation method and application thereof. Background technique [0002] Under the situation of "West-East Electricity Transmission, North-South Mutual Supply, and National Networking" of the State Grid, the high-voltage, long-distance, and large-capacity transmission lines have higher and higher requirements for the transmission performance and strength of cables used in transmission lines. . At present, the cables used in public places and high-rise buildings in my country basically use copper as the conductor (cable core) of the cable. Although copper has good electrical conductivity, its density is relatively high and its bending resistance is not good. It is increasingly difficult to meet the requirements of modern cables. Its power transmission performance and strength requirements. [0003] Graphene is a two-d...
